Let-7a sensitized HCC stem-like cells to cis-platinum induced self-renewal inhibition. a. Cis-platinum reduced sphere number through inhibition of Wnt1 expression. b. The combined use of cis-platinum and let-7a significantly decreased the sphere number, inhibiting the self-renewal ability of HCC stem-like cells through concurrent effects on Wnt signaling. c. Both let-7a and cis-platinum inhibited Wnt1 explression level, and exerted sygnergic inhibition on Wnt1 activity
